		My discussion post for the day:
	</p>
	<blockquote>
		<p>
			I can see why grades <strong>*should*</strong> be a numeric value.
			However, can we really label the lettered version of grades a number?
			Working by hand, we can certainly treat them as numbers.
			However, how do we enter &quot;A&quot; as a numeric value?
			Remember that to the computer, &quot;A&quot; and &quot;5&quot; are not the same thing.
			If we enter the numeric value &quot;5&quot;, we haven;t entered &quot;A&quot; as the problem asks us to do.
		</p>
		<p>
			I completely agree about the lost accuracy when dealing with letter grades.
			Not only do we have a smaller band of finite values, but, like you said, the &quot;F&quot; range is huge compared to the other ranges.
			We not only lose accuracy from rounding, but also lose accuracy due to lost scale.
